In The Blank Slate, Steven Pinker, one of the world's leading experts on language and the mind, explores the idea of human nature and its moral, emotional, and political colorings. With characteristic wit, lucidity, and insight, Pinker argues that the dogma that the mind has no innate traits-a doctrine held by many intellectuals during the past century-denies our common humanity and our individual preferences, replaces objective analyses of social problems with feel-good slogans, and distorts our understanding of politics, violence, parenting, and the arts. Injecting calm and rationality into debates that are notorious for ax-grinding and mud-slinging, Pinker shows the importance of an honest acknowledgment of human nature based on science and common sense.
Good book about precisely this (and in agreement with your statement) is cognitive psychologist Steven Pinker's 2002 book The Blank Slate: The Modern Denial of Human Nature.
Because they are scared of the slippery slope in questions of nature vs. nurture. Steven Pinker's book 'The Blank Slate: The Modern Denial of Human Nature' explores this topic and the cultural antecedents of naive nurturism.

Ah, the myth of the noble savage taken to evolutionary extreme.
I highly recommend Steven Pinker's "The Blank Slate" if you'd like to disabuse yourself of this pernicious old wives tale. Then his "Better angels of our nature" should fix you right up with a more accurate and informed view of the world and society we live in.
